Method and system for transmitting virtual reality video, method and system for downloading and playing virtual reality video, and computer equipment

Abstract

The invention provides a method and a system for downloading and playing a virtual reality video, a method and a system for transmitting the virtual reality video, computer equipment and a computer readable storage medium, and the method for downloading and playing the virtual reality video comprises the steps: establishing a video quality optimization model according to a viewpoint adaptive modeand a code rate adaptive mode; determining a next playing video clip according to the video quality optimization model in combination with the current playing video clip and the transcoding quality distortion information of the current playing video clip; and initiating a video downloading request, and downloading and playing the next playing video clip. The purposes of maximizing the quality in the window and reducing the quality jitter between video clips are achieved.

Description

technical field [0001] The present invention relates to the field of video technology, in particular, to a method and system for downloading and playing virtual reality video, a method and system for transmitting virtual reality video, computer equipment, and a computer-readable storage medium. Background technique [0002] Virtual reality video, also known as panoramic video or 360-degree video, is attracting widespread attention due to its full immersion, authenticity, and ease of production. It records natural images with three degrees of freedom or six degrees of freedom through panoramic cameras, thereby providing a sense of reality that cannot be achieved by existing ordinary videos. In recent years, with the maturity of virtual reality equipment, network and terminal technology, virtual reality video is being used more and more in applications such as film and television, games, medical care, and education. However, high-quality VR video services still face several c...

Problems solved by technology

[0004] Even if the advanced block transmission mode is adopted, there are still many challenges to provide users with high-quality video transmission services: 1) video block acquisition error

2) Boundary effects between blocks are obvious

3) The transition between video clips and clips is not smooth

In order to ensure the smooth playback of the video, the user needs to select the appropriate video bit rate according to the current bandwidth during the download process, so the adjacent video clips in time may be downloaded with different bit rates, eventually causing the transition of the video clip not smooth
